1. when i click on an email with a big excel attachment (7MB, 23000 rows) Airmail shows a beachball cursor and becomes unresponsive for ca 30-40 seconds. after the mail is opened the attachment displayed as an icon.

2. when i doubleclick the same email, a small preview window is opened and airmail freezes

When I hit the trash button on the top menu, the window freezes and looks like this. I have to force quit the app and re open it. No issues when archiving messages though. Happens every time I try to delete a message using the trash icon on the top row menu.

Moving one or more mails from inbox to local folders is hit or miss at best. Sometimes it takes several repeat attempts, sometimes it happens 10's of seconds or a minute after being actioned. Sometimes one can go ahead and do other moves which work or fail before the original occurs. It's the most annoying and time consuming part of Airmail on
Mac usage.

The delay between clicking a Message in List view and it being displayed is too long (> 100 ms) and makes the overall message browsing experience feel very sluggish. I'd like Messages to render instantly, possibly in a preview mode or as plain text. And I'd also like the keyboard based navigation of messages to not be delayed by the rendering of the message view. Ideally browsing is as snappy as navigating the Filesystem in Finder and Quicklook previews.

Up until recently, Airmail was a joy to use, now I can't get it to archive my FastMail emails. The archive function works perfectly on my Gmail accounts, but It freezes in FastMail. Attached is a screenshot of what happens when you hit the archive button. The performance has also degraded significantly. This bug appears to have gone away in the new beta, but I am not totally sure. Really this is a plead to release a fixed version as this has destroyed my email workflow.

Airmail is always the top most app in the activity monitor energy impact tab. Even with the app hidden, it's energy impact is constantly high and shifting. I only have a gmail and a exchange account with 2min inbox and 10 min folder refresh sync. This is really troubling and while I loved Airmail when I was on my iMac, it just seems to chew through my MacBook Pro battery.

Double clicking in search bar (e.g. to highlight the search text) makes the window full size (as if you've double clicked on the top bar), then the window disappears completely when you double click to make it back to the size you had before. The only way to get it back is to quit and open the program again.

Waiting for a large excel file preview to load can lock up the interface for quite some time. Instead, set a threshold value for attachment size above which attachments won't load a preview. Or set a timer that says if 5 seconds have gone by, cancel the preview and show an icon instead.

This is a bug report. I've been able to isolate an issue with an IMAP account to the airmail iOS app. When both the desktop and iOS appp are enabled, all my mail arrives as read. When I disable the IMAP account on the iOS app, the problem goes away.

A feature that I use a lot, is the keyboard shortcut V to move messages to a given folder. In Airmail 2, this used to be very fast as – I just pressed v and immediately proceeded by typing the first few letters of the folder name. Now I just upgraded to Airmail 3, and I find that I now have to wait a moment after I press v before I start writing the name of the folder, or else it misses the first letter. This is really annoying, so I hope you can make it work as well as it used to do.
